If money is not an issue - Buy a golden Tee, get a happ perfect solution switcher to make a dual machine in the golden tee cab, then completely mame this one after it is gutted of its boards/PC.
I am guessing that would rack up a bit of a bill, because i believe those perfect solutions are like $100, and there is enough demand for golden tee to make those around 500 or more, especially if you want a bit newer of a golden tee.
Since I am guessing money is not infinite, I would say go completely one way or another. Either bring it back to a pure silver strike, or mame it and sell the silver strike guts to help fund the rest of the cab. If your bring it back, taking out the joysticks and buttons should be easy to do, just fill the holes with bondo, cut a new piece of plexi and put on new art. I would be willing to bet stpcore, a member here, would be able to print you new control panel art.
And if you haven't played much silver strike yet, after a while it loses its thrill as a single player game, but is an excellent party game.
